なお、薬剤含浸網４６には、防虫薬剤と共に、常温で揮散性を有する有効成分を含有する芳香剤を保持させてもよい。芳香剤の含有量は任意であるが、芳香剤が有効に揮散し得る期間を防虫薬剤の有効成分が有効に揮散し得る期間に合わせると、芳香剤の芳香の強さを指標として防虫薬剤の有効成分の残量を確認することができる。 In addition, you may make the chemical | medical agent impregnation net | network 46 hold | maintain the fragrance | flavor containing the active ingredient which has volatility at normal temperature with an insecticide. The content of the fragrance is optional, but when the period during which the fragrance can be effectively volatilized is adjusted to the period during which the active ingredient of the mothballs can be effectively volatilized, the strength of the fragrance is used as an index. The remaining amount of the active ingredient can be confirmed.

なお本発明の薬剤保持部材は、上記した実施形態に限定されるものではなく、薬剤含浸網４６に代わってハニカム構造や、格子状構造を採用してもよい。さらに関連発明として線状構造が採用できる。関連発明として、薬剤保持部材は、液溜部と芯を有して液溜部に溜められた薬液を毛細管現象によって吸い上げて空気と触れさせる構成や、薬剤を固形化してその表面から薬剤を昇華させるものであってもよい。 Incidentally drug holding member of the present invention is not limited to the embodiments described above, a honeycomb structure or on behalf of the drug-loaded network 46 may employ rank child-like structure. Furthermore, a linear structure can be adopted as a related invention. As a related invention, the medicine holding member has a liquid reservoir portion and a core and sucks up the chemical liquid collected in the liquid reservoir portion by capillary action and comes into contact with air, or solidifies the drug and sublimates the drug from the surface. It may be allowed.

次に、本実施形態の防虫器１を構成する各部材の組み合わせ関係について説明する。
前記した薬剤保持部材４１は、外側部材５の溝部材１２に嵌合された状態で、外側部材５に保持されている。即ち一対の溝部材１２に薬剤保持部材４１の枠体５０の両辺が保持されている。 Next, the combination relationship of each member which comprises the insect repellent 1 of this embodiment is demonstrated.
The medicine holding member 41 described above is held by the outer member 5 in a state of being fitted to the groove member 12 of the outer member 5. That is, both sides of the frame body 50 of the drug holding member 41 are held by the pair of groove members 12.

内側部材６は、外側部材５の内側に挿入されている。即ち内側部材６は、外側部材５に対して入れ子状態となっており、内側部材６の側面部２１は、外側部材５の側面部１１の内側に挿入されている。より詳細には、内側部材６の側面部２１の外面が外側部材５の側面部１１の内面と接している。内側部材６の側面部２１と外側部材５の溝部材１２との間は接していない。したがって内側部材６は、外側部材５の中で、外側部材５と同心的に回転することができる。 The inner member 6 is inserted inside the outer member 5. That is, the inner member 6 is nested with respect to the outer member 5, and the side surface portion 21 of the inner member 6 is inserted inside the side surface portion 11 of the outer member 5. More specifically, the outer surface of the side surface portion 21 of the inner member 6 is in contact with the inner surface of the side surface portion 11 of the outer member 5. There is no contact between the side surface portion 21 of the inner member 6 and the groove member 12 of the outer member 5. Thus, the inner member 6 can rotate concentrically with the outer member 5 in the outer member 5.

蓋部材７は、外側部材５の天部及び側面の一部を覆う様に外側部材５に取り付けられている。ここで蓋部材７の小壁部２７の内面側に、外側部材５の側面に設けられた突起１７が係合し、蓋部材７は容易に外れない様に外側部材５に固定されている。
従って蓋部材７と外側部材５で天面、側面、底面が覆われた空間が形成され、前記した内側部材６はこの空間の中に保持されている。
また内側部材６の天部２０に設けられた摘まみ部２２は、蓋部材７の長孔２８に挿通され、先端部が蓋部材７から突出している。 The lid member 7 is attached to the outer member 5 so as to cover the top part of the outer member 5 and a part of the side surface. Here, the protrusion 17 provided on the side surface of the outer member 5 is engaged with the inner surface side of the small wall portion 27 of the lid member 7, and the lid member 7 is fixed to the outer member 5 so as not to be easily removed.
Therefore, a space in which the top surface, the side surface, and the bottom surface are covered with the lid member 7 and the outer member 5 is formed, and the inner member 6 described above is held in this space.
Further, a knob portion 22 provided on the top portion 20 of the inner member 6 is inserted into the long hole 28 of the lid member 7, and a tip portion projects from the lid member 7.

この様に防虫器１は、外側部材５によって底が覆われ、外側部材５と内側部材６によって周面が覆われ、蓋部材７によって天面が覆われた筐体２を有する。そして筐体２の内部の空隙部であってその中央に、防虫薬剤（防虫剤３）が含浸された一枚の薄い薬剤含浸網４６が帆の様に立てられた状態となっている。そのため筐体２の内部に存在する部材（薬剤含浸網４６及び溝部材１２）が占める体積割合は、極めて小さく、筐体２の内部には、大きな空間３５がある。そしてこの空間は、薬剤の拡散空間３５として機能する。
また筐体２を構成する外側部材５と内側部材６は、別個の部材であり、且つ両者はいずれも円筒形であるから、両者は相対回転を許す。即ち摘まみ部２２を操作することにより、外側部材５内で、内側部材６を回動することができる。 As described above, the insect repellent 1 includes the housing 2 whose bottom is covered by the outer member 5, whose peripheral surface is covered by the outer member 5 and the inner member 6, and whose top surface is covered by the lid member 7. A thin drug-impregnated net 46 impregnated with an insect repellent (insect repellent 3) is erected in the middle of the space inside the housing 2 like a sail. Therefore inside member (drug-loaded network 46 and the groove member 12) which accounts volume ratio in the presence of housing 2 is very small, in the interior of the housing 2, a large space 35 there. This space functions as a drug diffusion space 35.
Further, since the outer member 5 and the inner member 6 constituting the casing 2 are separate members, and both are cylindrical, both allow relative rotation. That is, by operating the knob 22, the inner member 6 can be rotated within the outer member 5.

そして外側部材５と内側部材６の側面部１１，２１は、同一形状であって同一配置の開口１５，２３が設けられているから、一定の回転姿勢においては、開口１５，２３同士が一致して連通し、筐体２の内外を連通する共通開口５３が形成される。
一方、他の一定の回転姿勢においては、開口１５，２３同士が完全にずれ、筐体２の内外が密閉される。即ち一方の開口が他方の開口同士の間に位置し、一方の開口が他方の壁で封鎖される状態となる。そのため外側部材５と内側部材６の側面部１１，２１の開口１５，２３は、互いに封鎖され、筐体２内が密閉状態となる。 The side surfaces 11 and 21 of the outer member 5 and the inner member 6 have the same shape and the same arrangement of openings 15 and 23. Therefore, the openings 15 and 23 coincide with each other in a fixed rotational posture. Thus, a common opening 53 that communicates between the inside and outside of the housing 2 is formed.
On the other hand, in other fixed rotational postures, the openings 15 and 23 are completely displaced from each other, and the inside and outside of the housing 2 are sealed. That is, one opening is located between the other openings, and one opening is sealed with the other wall. Therefore, the openings 15 and 23 of the side surfaces 11 and 21 of the outer member 5 and the inner member 6 are sealed from each other, and the inside of the housing 2 is sealed.

次に本実施形態の防虫器１の機能について説明する。
本実施形態の防虫器１を輸送したり、保管する場合、即ち使用しない場合には、内側部材６のスリット状の開口２３を外側部材５のスリット状の開口１５に対してずらし、筐体２を密閉された状態とする。
ここで本実施形態では、筐体２の内部に薬剤の拡散空間３５があるから、揮発した薬剤のガスがこの内部空間３５に溜まる。拡散空間３５内の薬剤濃度は、時間の経過と共に上昇し、ついては飽和状態となる。 Next, the function of the insect repellent device 1 of this embodiment will be described.
When transporting or storing the insect repellent device 1 of this embodiment, that is, when not using it, the slit-like opening 23 of the inner member 6 is shifted with respect to the slit-like opening 15 of the outer member 5, and the housing 2 Is in a sealed state.
Here, in the present embodiment, since there is a drug diffusion space 35 inside the housing 2, the volatilized drug gas accumulates in the internal space 35. The concentration of the drug in the diffusion space 35 increases with time, and then becomes saturated.

そして室内等で防虫器１を使用する場合には、摘まみ部２２を操作して内側部材６を回転させ、外側部材５と内側部材６の開口１５，２３を合致させて筐体２の内外を連通する共通開口５３を形成させる。
その結果、拡散空間３５に溜まった高濃度の薬剤ガスが外部に放出される。さらに筐体２の内部が通風可能な状態となり、新たに導入された空気が薬剤保持部材４１と接し、薬剤保持部材４１に含浸された防虫薬剤（防虫剤３）が気化して共通開口５３から設置室内等に流れる。
この様に、共通開口５３を開いた際に、高濃度の薬剤ガスが流れ、さらに新たに防虫薬剤（防虫剤３）が気化して設置室内等に流れるので、室内は短時間の内に薬剤の有効濃度に達する。
また本実施形態では、防虫器１の全体形状が円柱形であり、共通開口５３は周面に均衡に配されているから、室内の風向きに関係なく筐体２内に空気が導入され、防虫薬剤（防虫剤３）の気化が円滑に進む。 When the insect repellent device 1 is used indoors or the like, the knob 22 is operated to rotate the inner member 6 so that the outer member 5 and the openings 15 and 23 of the inner member 6 are aligned to match the inside and outside of the housing 2. A common opening 53 that communicates with each other is formed.
As a result, the high-concentration drug gas accumulated in the diffusion space 35 is released to the outside. Further, the inside of the housing 2 is in a state in which ventilation is possible, the newly introduced air comes into contact with the drug holding member 41, and the insect repellent drug (insect repellent 3) impregnated in the drug holding member 41 is vaporized and is discharged from the common opening 53. It flows into the installation room.
In this way, when the common opening 53 is opened, a high-concentration chemical gas flows, and a new insect repellent (insect repellent 3) is vaporized and flows into the installation room or the like. Reaches an effective concentration.
Further, in this embodiment, since the overall shape of the insect repellent device 1 is a cylindrical shape and the common opening 53 is arranged in a balanced manner on the peripheral surface, air is introduced into the housing 2 regardless of the wind direction in the room, and the insect repellent The vaporization of the drug (insect repellent 3) proceeds smoothly.

共通開口５３を開いた後は、室内の所定の板に防虫器１を設置し、あるいはフック部３０を利用してつり下げる。 After opening the common opening 53, the insect repellent device 1 is installed on a predetermined plate in the room or suspended using the hook part 30.

また使用を停止する時には、再度摘まみ部材２２を操作して共通開口５３を閉じる。
防虫器１を使用しない場合は、共通開口５３を閉じた状態のままで置くこととなるが、共通開口５３を開くには、摘まみ部材２２を円弧状に動かして内側部材６を回転させなければならないから、犬や猫等のペットでは不可能であり、幼児であっても困難である。そのため共通開口５３を開くことは困難であり、安全性が高い。 When the use is stopped, the knob 22 is operated again to close the common opening 53.
When the insect repellent 1 is not used, the common opening 53 is placed in a closed state, but in order to open the common opening 53, the knob member 22 must be moved in an arc shape and the inner member 6 must be rotated. Therefore, it is impossible for pets such as dogs and cats, and it is difficult even for infants. Therefore, it is difficult to open the common opening 53, and the safety is high.

また使用状態においても、防虫薬剤（防虫剤３）は、筐体２の奥にあり、且つ共通開口５３は狭いので、防虫薬剤に直接手指が触れることはない。 Even in use, the insect repellent (insect repellent 3) is in the back of the housing 2 and the common opening 53 is narrow, so that the finger does not directly touch the insect repellent.

以上説明した実施形態では、外側部材と内側部材が共に円筒形であるものを開示したが、図５の様な円板状の防虫器６０であってもよい。即ち背の低い円筒形の外側部材６１に円板状の内側部材６２を内蔵し、外側部材６１の天面と、円板状の内側部材６２とに同一形状の開口６５を設ける。また内側部材６２の一部を外側部材から露出させて摘まみ部６６とし、摘まみ部６６を回転させることによって円板状の内側部材６２を回動させる。 In the embodiment described above, the outer member and the inner member are both cylindrical. However, a disc-shaped insect repellent device 60 as shown in FIG. 5 may be used. That is, a disk-shaped inner member 62 is built in a short cylindrical outer member 61, and an opening 65 having the same shape is provided on the top surface of the outer member 61 and the disk-shaped inner member 62. Further, a part of the inner member 62 is exposed from the outer member to form a knob 66, and by rotating the knob 66, the disk-shaped inner member 62 is rotated.

さらに図６の様に示した防虫器７０の様に円錐台形状の筐体７１を採用することもできる。図６において、７２は摘まみ部である。 Furthermore, a truncated cone-shaped casing 71 can be adopted as in the insect repellent device 70 shown in FIG. In FIG. 6, reference numeral 72 denotes a knob.

上記した各実施形態では、使用時に、外側部材の開口と、内側部材とを完全に一致させたが、重なり部分の面積を調節して共通開口５３の面積を調節することともできる。その結果、設置する部屋の大きさに合わせて、蒸散量を調節することもできる。
また上記した各実施形態例は、使用の際の外形形状と、不使用時の外形形状がほとんど変化しないという特徴もある。 In each of the above-described embodiments, the opening of the outer member and the inner member are completely matched during use. However, the area of the common opening 53 can be adjusted by adjusting the area of the overlapping portion. As a result, the amount of transpiration can be adjusted according to the size of the room to be installed.
In addition, each of the above-described embodiments has a feature that the outer shape when used and the outer shape when not used are hardly changed.

また上記した実施形態の防虫器防虫器１，６０，７０は、いずれも外側部材と内側部材を相対回転させて共通開口５３を開閉するものであるが、外側部材と内側部材を直線的に相対移動させて共通開口５３を開閉させることも可能である。 In addition, the insect repellents 1, 60, and 70 of the above-described embodiments all open and close the common opening 53 by rotating the outer member and the inner member relative to each other. It is also possible to open and close the common opening 53 by moving it.

図７、図８は、外側部材と内側部材を直線的に相対移動させて共通開口を開閉させる構成を示す。即ち図７は、本発明の第四実施形態の防虫器の斜視図であり、図８、使用状態における図７の防虫器の断面図である。
図７、図８に示す防虫器７５は、薄型直方体の筐体７６の内部に、薬剤保持部材７８が内蔵されたものである。また筐体７６は、樹脂で作られたものであり、図８の様に外側部材７７と内側部材８０によって構成されている。 7 and 8 show a configuration in which the common member is opened and closed by linearly moving the outer member and the inner member relative to each other. That is, FIG. 7 is a perspective view of the insect repellent device of the fourth embodiment of the present invention, and FIG. 8 is a cross-sectional view of the insect repellent device of FIG.
The insect repellent 75 shown in FIGS. 7 and 8 has a medicine holding member 78 incorporated in a thin rectangular parallelepiped housing 76. The casing 76 is made of resin, and includes an outer member 77 and an inner member 80 as shown in FIG.

外側部材７７は枠状であり、底部８１と、正面部８２、裏面部及び左右の側面部８３，８４を持つ。外側部材７７の天面は開放されている。外側部材７７の内部は空洞である。即ち外側部材７７は５面が囲まれた枠体である。 The outer member 77 has a frame shape and has a bottom portion 81, a front portion 82, a back surface portion, and left and right side portions 83 and 84. The top surface of the outer member 77 is open. The inside of the outer member 77 is a cavity. That is, the outer member 77 is a frame body surrounded by five surfaces.

外側部材７７の正面部８２及び裏面部には複数のスリット状の開口８５が外側部材７７の外形線に対して平行に設けられている。また外側部材７７の左右の側面部８３，８４には、正方形状の開口８７が等間隔に複数設けられている。 A plurality of slit-shaped openings 85 are provided in parallel to the outline of the outer member 77 on the front surface 82 and the rear surface of the outer member 77. A plurality of square openings 87 are provided at equal intervals on the left and right side surfaces 83 and 84 of the outer member 77.

内側部材８０は、本体部８９とフック９０によって構成されている。内側部材８０の本体部８９は、６面が覆われた枠体であり、前記した外側部材５の開口８５，８７と同一の位置に同一の大きさ及び形状の開口が設けられている。
内側部材８０の天面にフック９０が設けられている。 The inner member 80 includes a main body 89 and a hook 90. The main body portion 89 of the inner member 80 is a frame that covers six surfaces, and openings having the same size and shape are provided at the same positions as the openings 85 and 87 of the outer member 5 described above.
A hook 90 is provided on the top surface of the inner member 80.

本実施形態の防虫器７５では、薬剤保持部材７８は、内側部材８０の中に挿入されている。そして薬剤保持部材７８が内蔵された状態の内側部材８０が、外側部材７７の中に摺動可能に内蔵されている。
即ち図７の様に、内側部材８０の本体部８９が外側部材７７内に完全に収納された状態にすることができ、この状態から図８の様に内側部材８０を摺動させて外側部材７７に対して相対移動させ、内側部材８０の一部が外側部材７７から突出する状態に変化させることができる。 In the insect repellent 75 of the present embodiment, the medicine holding member 78 is inserted into the inner member 80. The inner member 80 in which the medicine holding member 78 is built is slidably built in the outer member 77.
That is, as shown in FIG. 7, the main body 89 of the inner member 80 can be completely accommodated in the outer member 77. From this state, the inner member 80 is slid as shown in FIG. The inner member 80 can be changed to a state in which a part of the inner member 80 protrudes from the outer member 77.

そして外側部材７７と内側部材８０の本体部８９は、同一形状であって同一配置の開口８５，８７が設けられているから、図８の様に内側部材８０の本体部８９が外側部材７７から突出している場合は、外側部材７７と内側部材８０の開口同士が一致して連通し、筐体７６の内外を連通する共通開口９１が形成される。
防虫器７５を使用する際には、図８の様に内側部材８０の一部を外側部材７７から引出し、筐体７６の内外を連通させて内部の薬剤保持部材７８を露出させる。 Since the outer member 77 and the body member 89 of the inner member 80 have the same shape and are provided with openings 85 and 87 having the same arrangement, the body member 89 of the inner member 80 is separated from the outer member 77 as shown in FIG. When projecting, the openings of the outer member 77 and the inner member 80 are in communication with each other, and a common opening 91 that communicates the inside and outside of the housing 76 is formed.
When the insect repellent 75 is used, a part of the inner member 80 is pulled out from the outer member 77 as shown in FIG. 8, and the inside and outside of the housing 76 are communicated to expose the internal medicine holding member 78.

一方、図７の様に内側部材８０の本体部８９が外側部材７７内に完全に収納されている場合は、外側部材７７と内側部材８０の開口がずれ、筐体７６の内外が密閉される。
図７は、防虫器７５を使用しない場合の形態であり、筐体７６の内外が密閉されるので薬剤保持部材７８は外気に触れず、薬剤の消費が阻止される。 On the other hand, when the main body 89 of the inner member 80 is completely accommodated in the outer member 77 as shown in FIG. 7, the openings of the outer member 77 and the inner member 80 are displaced, and the inside and outside of the housing 76 are sealed. .
FIG. 7 shows a case where the insect repellent 75 is not used. Since the inside and outside of the housing 76 are sealed, the medicine holding member 78 does not touch the outside air, and the consumption of the medicine is prevented.

図７、図８に示した実施形態では、外側部材７７及び内側部材８０にスリット状の開口８５を設け、この開口８５を外側部材７７の外形線に対して平行に配置したが、開口８５の形状等は任意であり、例えば図９に示す防虫器９２の様に斜めに配列してもよい。
防虫器９２の構造は、図７及び図８の防虫器７５と同一であるから、同一の部材に同一の番号を付して詳細な説明を省略する In the embodiment shown in FIGS. 7 and 8, the outer member 77 and the inner member 80 are provided with slit-like openings 85, and the openings 85 are arranged in parallel to the outline of the outer member 77.
